The coefficient can be indicative of the material abrasion resistance properly and directly used to calculate the safety gas velocity in the convectionheatingsurface of coal-fired boilers.
并用它表征塑性材料的抗磨性能。该系数可直接应用于计算燃煤锅炉对流受热面的安全烟速。

The calculate formula premise of the residual life of boiler convectionheatingsurface is pointed out, and the cause of heating surface wearing due to the quality decline of coal is analyzed.
Finally, this paper analyses the data which are measured in new heating transfer appliance with the pin fins tubes and explains the effect of using the pin fins tubes for convectionheatingsurface.
